WATER-HEATER FOR COOKING-RANGES, 800.

SPECIFICATION forming part of Letters Patent No. 242,383, dated May 31, 1881.

Application filed September 17, 1880. (No model.)

To all whom it may concern Beit known that I, NATHANIEL M. SIMoNDs, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Water-Heaters for Cooking Ranges, Stoves, &c., of which the followingis a full, clear, and exact description, reference bein 'had to the accom an in drawin s mak- O D D 7 ing partof this specification.

My invention relates to an improvement in those devices hich consist of a water-reservoir formed with a horizontal trunk or chamber inserted through the side wall or plate of the fuel-chamber.

My improvement consists in providing said trunk or chamber with a horizontal plate to separate the current of cooler water flowing toward the fire from the hotter water flowing back into the tank or reservoir.

In the drawings, Figure 1 shows theimprovement in vertical section at 00 a Fig. 2, with parts of the range and hot-water tank in section on the same plane, and parts in elevation. Fig. 2 is a horizontal section of the improvement and water-tan k and part of the range at 00 a, Fig. 1. Fig. 3 is an end view of the water-trunk from the inside of the tank, showing part of the wall of the tank.

A is the range, having side wall, A, and furnace or firechamber B. The wall A is made with an aperture to receive the end 0 of the water-trunk, which thus forms part of the furnace or fire-wall.

I) is a flange fitting the outside of the rangewall A, and attached thereto by bolts d, or 0therwise, so as to makea sufficiently tight joint. The other end, 0, of the water trunk or chamher is connected to the water-tank F by a flange-joint, or otherwise, and is in open communication with the tank, so that water flows freely from and to the tank, as'shown by arrows. I have shown the water-trunk with a flange, D, lying againstthe outside of the tank, and a collar-plate, D inside the tank, surrounding the orifice e c, with bolts (1 extending through the flange, tank, and collarplate. The joint between the water trunk and the tank must be water-tight.

E is the diaphragm or division-plate dividing the water-trunk into two water ways or passages, e 0, one beneath the other. The division-plate E does not extend across the whole area of the water-trunk, but there are at the corners orifices e e for the ascent of the heated water from the water-way e to that 6. Thus the water flows from the tank to the fireplate 0 beneath the division-plate E, and returns to the tank above the division-plate or diaphragm along passage 0.

The diaphragm E may be attached to or in contact with the fire-plate c, or it may be out of contact with it, so as to leave a long and narrow orifice for the upward flow of water across the whole width of the fire-plate.

The division-plate or diaphragm E may be made in one piece with the water-trunk, or may consist of a separate plate or plates inserted therein. My preference is to make it in one piece with the water-trunk. The trunk is inserted through either side or back of fuel or fire chamber.

The diaphragm E may extend any suitable distance into the water tank, receptacle, or chamber F, the most available means for the construction being by a separate plate, E. (See dotted lines in Figs. 1 and 2.)

I have shown the tank F of a cylindrical form, but-do not confine myself to any special shape. For instance, it maybe of rectangular flattened form extending horizontally, as a steam heating or cooking table.

I claim as my invention 1. The combination, with the fire-chamber or furnace B and water tank or receptacle F, of the water trunk or chamber 0 C, with a division, E, therein, substantially as and for the purpose set forth.

2. The combination of furnace B, watertrunk O 0, and tank F, and the extensionplate E, operating substantially as set forth.
